A Flexible LDPC/Turbo Decoder Architecture [PDF]
, 2010 Low-density parity-check (LDPC) codes and convolutional Turbo codes are two of the most powerful error correcting codes that are widely used in modern communication systems. In a multi-mode baseband receiver, both LDPC and Turbo decoders may be required.

Improving 3D-Turbo Code's BER Performance with a BICM System over Rayleigh Fading Channel [PDF]
Radioengineering, 2016 Classical Turbo code suffers from high error floor due to its small Minimum Hamming Distance (MHD). Newly-proposed 3D-Turbo code can effectively increase the MHD and achieve a lower error floor by adding a rate-1 post encoder.

Recurrent neural network based turbo decoding algorithms for different code rates
Journal of King Saud University: Computer and Information Sciences, 2022 Application of deep learning to error control coding is gaining special attention and neural network architectures on decoding are approached to compare with conventional ones. Turbo codes conventionally use BCJR algorithm for decoding.

Spatially coupled turbo codes [PDF]
2014 8th International Symposium on Turbo Codes and Iterative Information Processing (ISTC), 2014 In this paper, we introduce the concept of spatially coupled turbo codes (SC-TCs), as the turbo codes counterpart of spatially coupled low-density parity-check codes. We describe spatial coupling for both Berrou et al. and Benedetto et al. parallel and serially concatenated codes.
